. Application lediArpril 10, 1925. Serial No. 22,013.

This invention relates to a separator kand particularly to a machine adapted for useasa bean huller. lOne .object of the inventionis to providemeans for separating out stones and other injurious matter from the beans before they reach the hulling Zone.

Another object is to provide means for the` accumulation of such material after it has beenseparated out. Other objects will appear from time to Vtime throughout the speciy cationand claims. Y

Like 'parts are indicated by hroughout. f

A represents generally the housing which encloses the mechanism. B is the enclosing like characters yand supporting housing within which a conveyor preferably of the belt type :is mounted and which'conveys the material to the sep arating zone. 'C is the'belt vconveyor prov `vided with Vslats or. cleats C1.' It revolves at one endv about a pulley C2 which is car'- ried upon a shaft C3. C4 isa ijloor beneathl the belt. C5 is an extended covering member which forms in effect'an extension of the floor C4 and is curved about the shaft C?.

It serves among other purposes to prevent Vmaterial which is brought in von the conveyor from falling down and escapingl the stone picker drum. y

D is a shaking pan. Its lower end is slidably mounted on the plate D1` and adjacent its upper end it is engaged .by one or more rocker arms D2 carried on the rock shaft vD3 which is vjournaled in bearings D4 on. the feeder fra-me; At one end of the rock shaft D? is a lever arm D5 which has attached to its lower end a link D which is mounted onv a crank carried by the sprocket vwheel D7 driven in the manner described below. The rotation of the sprocket wheel D7 through the link moves the rocker arms and the shaft D3. Thus the shaker pan is moved. y

lE is la concave providedwith removable teeth El-and iny co-operation with it' is the cylinder F mounted on a. shaft F1 which `It is preferably metallic.

oafries at its outer end a driving kPulley adapted 'to be driven bythe belt F5 from'any suitable power source. Mounted in the cyl-` inder F areremovable teeth y The ,detailsY of the concave and its associated parts willv not be. described furtherv as they form no part ofthe present invention. c

Mounted above the shaker pan on a shaft G is a stone picker.. cylinder G1- provided, with teeth G2 which may be removable andV are preferably rearwardly bent las shown.,

The shaft G carries at lits outer lend a belt pulley G3 which isin contact with and driven i bya belt F3.

which through a chain H1- drives the sprocket whe-el H2 on the corresponding end of the carrier shaft C3, and thus the'carrier shaft- 1s` driven. second sprocket I-which by means vof the chainl1 drivesvthe lsprocket D7,qand=thus operates the shaker pan. v' i Between the carrier and the stone picker cylinder and. slightly belowthe carrier is a shield J. This shield runs transversely Mounted :on the` shaft G islasprocket Hv The shaft G3. also .carries a across the machine throughout substantially Y the width of the carrier. lt may be iieXible and under certain circumstances the mem-Y bers C1 of the carrier will strike -it and de-v i Y fleet it slightly downward, andit is. to permit this that it'isgenerally preferably-Herd blc. Itis removably fastened to a` trans# verse member J1. K is a fdeiiector plate situated-in the upper part of the machine.-

L is a stone receiving compartment having an open side kL'1 .in which is hung aV swinging curtain L2 preferably flexible. In the top of the 'compartment L is hinged a cover L3. The compartment L has; in its bottom', raised slat members *Lt M is a` vice, still `it will beobvio'us that manyv changes' might be Vmade in size, shape and arrangement of parts without departing materially from the spiritof my invention.; andv I wish, therefore, that 4my showing bev taken as in a sense diagrammatic. Particularly wherein the specification and'clainis 'lzhave hulling beans.

hulled are placed upon a carrier and by it ed to the machine They pass olif the end of the carrier and on falling downward toward the shaker pan the teeth of rthe stone picker cylinder strike the beans. To some extent they are .separated by the operation ofthe cylinder. Stones, clods of dirt vand other foreign matter which is fed-fin with j the beans will be struck by the teeth and be 4driven upward against the deflector plate.

.F rom this they will be deflected against the leXible curtain and the heavier matter will swing the curtain inward and will pass through the open side of the stone receiving chamber and will lodge therein. Some' o the lighter matter, such as beans'and bean pods may be driven upward and deflected against the curtain, and they willnot be sulficiently heavy to swing th-c curtain aside and therefore they will `drop down again into the machine. v

X` indicates a stone at the time itis struck. It passes along the path X1 being deflected and finally lands in the stone compartment in the position X2. 'Y Y are beans, or bean pods which are driven upward by the stone picker and strike some portion of' the deflecting apparatus, but being 'too light to move the curtain fall back again into the carrier and so into the machine.

I claim:
